SUMMARY: ultra60 reboots with memory errors

Hi ,

My problem is still not solved  , I got few replies which  suggest that it
is a hardware problem only .I will call sun when my machine reboots next
time( it hasn't rebooted since I posted this message) . I am sending this
summary to share the suggestions I got .I will post another summary when my
problem is completely solved .

Thanks to all those who replied .

I got replies from
roman.pestka@CommerzbankIB.com,
pmora@cgob.junta-andalucia.es,
joe.fletcher@metapack.com,
willief@base-2.com

roman suggested that  "This is a reboot initiated by the improved kernel
Ecache error handling, it
is most likely not a memory issue but a CPU issue." and "this is  a
hardware issue, nothing to do with a PCI card."

pmora had faced similar problems with a 450 , got his cpu replaced thrice
before his problem got solved,  but he dont beleive that all his previously
replaced cpu were bad .

joe fletcher  told me to install latest GLM patches if there a symbios
logic diff scsi card was installed on my machine . Well I dont have any
such card in my system .

willief  suggested to try out few things like  Check to make sure memory
modules are seated perfectly into their sockets. He doubted  that
motherboard could be faulty. He also beleived that PCI card could not cause
this problem. Although he later suggested me to give it a try(replacing or
taking out the pci card) . He writes "The last thing I believe you
mentioned was a PCI card. You never know. Although the PCI bus is isolated
from memory via the PCI interface chip on the motherboard. Its worth a
try."

Thanks
Surender
